Scopas tang nipping at kenya tree?

Hello all! First post on 3reef here! I just bought a beautiful scopas tang within the last week, and being saturday it's my first day this week seeing him during the day but he's been nipping at my kenya tree. I don't see it as necessarily a huge issue, he can eat it, it grows fast! But I don't want him to start going after other things.

notes-75 gallon with 45 long sump, he is about 3.5-4 inches, in with three clowns (i can elaborate...0.0), three firefish, a scooter dragonet, a watchman goby, a melanurus wrasse, a chromis, a damsel, and a purple dottyback.
Many corals mainly soft and lps with three or four sps.

this is the only coral he is bothering at all, and the coral seems to open up within a couple of minutes of his nipping....

i supplement him with some garlic seaweed, unsure of the exact type, it's downstairs and i am being lazy haha.

any help would be greatly appreciated...

 

Welcome to 3reef.

Is the coral in his "swim path"?
